It is very important to verify generated setup errors in cancer therapy by using a high energy radiation and to perform the precise radiation therapy. Specially, the verification of treatment position is very crucial in special therapies like fractionated stereotatic radiotherapy (FSRT). The FSRT uses normally high-dose, small field size for treating small intracranial lesions. To estimate the developed FSRT system, the isocenter accuracy of gantry, couch and collimator were performed and a total of inaccuracy was less than ${\pm}1mm$. Precise beam targeting is crucial when using high-dose, small field size FSRT for treating small intracranial lesions. The EPID image of the 3mm lead ball mounted on the isocenter with a 25mm collimator cone was acquired and detected to the extent of one pixel (0.76mm) after comparing the difference between the center of a 25mm collimator cone and a 3 mm ball after processing the EPID image. In this paper, the radiation treatment efficiency can be improved by performing precise radiation therapy with a developed video based EPID and FSRT at near real time

This study has been conducted on 213 students in 4-year universities located in the regions of Daejeon and Chungnam in order to investigate a method to develop a smart device based culinary education application and the results and development method were as follows. First, the most often used smart device was a smart phone, which is used for over 5 hours a day and mainly used for SNS. Second, they utilized a smart device for language and major study during their spare time, wanted educational contents most and thought them useful for learning. Third, most of the students were positively aware of the necessity and learning effects of culinary education applications, and the response rate to utilize the application once a week was highest. Also, they hoped various recipes and simple cuisine and craftsman cooking. Therefore, the functions of SNS mostly often used by students should be added to promote interaction between teachers and students. And more contents should be made for students to use easily in moving or in their spare time. Furthermore, various videos of teaching and theoretical information should be included. And the applications focused on recipes and simple and craftsman cooking should be developed and uploaded on a school homepage and on popular portal sites so that students can easily utilize them.

To generate on-board digital tomosynthesis (DTS) for three-dimensionalimage-guided radiation therapy (IGRT) as an alternative to conventional portal imaging or on-board cone-beam computed tomography (CBCT), two clinical cases (liver and bladder) were selected to illustrate the capabilities of on-board DTS for IGRT. DTS images were generated from subsets of CBCT projection data (45, 162 projections) using half-fan mode scanning with a Feldkamp-type reconstruction algorithm. Digital tomosynthesis slices appeared similar to coincident CBCT planes and yielded substantially more anatomic information. Improved bony and soft-tissue visibility in DTS images is likely to improve target localization compared with radiographic verification techniques and might allow for daily localization of a soft-tissue target. Digital tomosynthesis might allow targeting of the treatment volume on the basis of daily localization.

Objectives : To address most probable and suitable method for designing clinical trial intervening Traditional Korean Herbal Medicine on hwa-byung. Study Design : A systematic review of research studies of complementary and/or alternative medical(CAM) treatment of depression, and of domestic clinical trials of Traditional Korean Medicine, and of Chinese clinical trials of Traditional Chinese Medicine. Methods : Randomized, controlled trials(RCTs) of treatment of depression intervening herbal medicine were searched through MEDLINE, Cochrane Library, and CNKI databases. Also, domestic RCTs intervening Traditional Korean Herbal Medicine were searched through Korean Traditional Knowledge Portal and Korean studies Information Service System(KISS). Studies were evaluated using Iadad scale and self-designed tool for this study. Results : Thirty four RCT studies( 10 from MEDLINE, 16 from CNKI, 8 domestic studies) of herbal medicine met inclusion criteria. Mean Jadad score of studies published in English was 2.8${\pm}$0.79, in Chinese 1.94${\pm}$0.77, and in Korean 2.75${\pm}$0.71. Twenty one percent of studies included pattern differentiation in their inclusion criteria. Twenty nine percent of studies used combined treatment of herbal and conventional medicine. Among studies on depression, 9% included Complementary Medical assessing tools. Conclusions : There is shortage of domestic clinical trial involving herbal medicine. In China, studies tend to focus on investigating effect of Combined treatment of herbal and conventional medicine on depression.

In the current study, we surveyed the status of graveyard lawn maintenance in Korea. The lawn maintenance information was obtained from the vicarious companies registered on the internet portal site and the Forestry Federation of Korea, and the questionnaire investigation from Primary Agricultural Cooperatives (Nonghyup). In all provinces surveyed, individual graves were maintained on a $66m^2$ (20 Pyeong) basis. The vicarious maintenance of graveyard lawn was carried out 1~5 times a year, and the maintenance cost increased as the number of times increased. Mowing the grass around a grave (Beolcho) was mainly done before the Korean Thanksgiving Day (Chuseok). The number of Beolcho was steadily increased from 2013 to 2015, and the price was getting higher and higher. Gyeonggi province had the highest cost, and Jeolla had the lowest cost. Regardless of the year, the number of orders received were higher in Gyeongnam > Gyeongbuk > Jeonnam province in order. Most of the reason for requested Beolcho was because the client lives in the area far from the graveyard. The direction of the cemetery was very varied. According to the survey, the all grass were zoysiagrass (Zoysia japonica), and grass coverage rate of the graves was 35.4~71.9%. Through questionnaire investigation, the reason why the density of grass was lowered was because the periodic management of weeds and fallen leaves was insufficient. Further research on the maintenance of graveyard in the future will be necessary.

The purpose of this study is to analyze the process of growth of parental empowerment of the family of the children with development disabilities in an online parental community. For this purpose, 250 posts were selected from a web-forum of an online-community(internet CAFE) for patients with developmental disabilities in a Korean portal site. In addition, the selected posts were analyzed based on the grounded theory method. The results showed that the parents with high risk children for developmental disabilities interacted with each other in short answers, self-addressing, and discussion type interactions under the causal condition in which the subject parents were in need of help and sympathy. The factors that significantly affected the focus event, which is the interactive communication between the posters of the original threads and replies, included the moderating conditions based on whether the conversation was respectful, friendly, or for general evaluation, as well as the contextual condition of exclusive attitudes. The strategies of the interactions were composed of two categories of self-reflections and sharing through a human relationship. The results of these interactions were either further interactions (sharing) or shying away. With regard to the process of reinforcing the collective empowerment of the family, the 'determination,' 'tips,' and 'empathy' models were used for the explanation of the process. Lastly, we discovered that trust, support, continuous interactions, specific and practical information, as well as provision of diversified perspectives through collective experiences are necessary to achieve such improvement of collective family empowerment.
